1 Claim. (Cl. 117-55) The present invention relates to protective coatings, applications and dressings for skins and leather, and particularly to a special leather protective coating for the sole of a shoe.

The main object of my invention is to provide coating means for protecting and preserving leather shoe soles in order to provide an effective protection against wear, and great strength and durability thereto.

Another object of the invention is to have a special coating for shoe sole and heel leather and the like, that may readily be applied by a brush, sponge or rag in simple manner.

A further object is to have such a protective coating for leather soles and heels that forms an efiective wear surface and is both reasonable in cost and also etfective H1 use.

Other objects and advantages of my invention will appear in further detail as the specification proceeds.

It is, of course, well known that shoe leather has a tendency to wear and all too easily become perforated and worn out, this being partly due to the roughness of the street pavements to which the leather is exposed during walking. Sometimes, also, the shoes are more or less carelessly brought forcibly against various objects that tend to cut, tear and perforate the leather with disastrous results.

Upon considering this problem, it has occurred to me that a special protective wear coating for protecting shoe leather from direct contact with the pavement, should be available to coat it and thereby take the actual wear and tear of use. As a result, I have succeeded in producing a very efiective leather wear coating as already outlined, which I shall now proceed to describe in detail in the following.

Hence, in the practice of my invention, I combine three ingredients, tar, alcohol and cement in certain nited States Patent 2,731,363 Patented Jan. 17, 1956 proportions to form a composition of matter that can readily be applied to the surface of the shoe leather sole and heel in various ways. In other words, about ten percent of cement such as Portland cement or other cement such as is available in hardware stores generally is added to about forty-five percent each of ethyl or methyl alcohol and common tar and well mixed. The resulting composition may be applied by means of a knife, spatula, stick, sponge or rag or even a stiff brush to form a thin coating on the leather sole and also on the heel it also of leather, after which it is allowed to dry for several hours, even twenty-four hours, if desired.

However, the shoe sole and heel to be treated should first be washed and then wiped thoroughly, after which these parts are treated with ethyl or methyl alcohol and allowed to dry. When thus dried, the composition or novel dressing above described is applied as already mentioned and dried very thoroughly. The leather sole and heel will then be provided with a tough and strong renewable wear surface that will withstand rough usage without exposing the leather of the sole and heel or wearing out the same.

Manifestly, variations may be resorted to, and features may be modified or used without others within the scope of the claim.

Having now fully described my invention, 1 claim:

The method of treating and thereby preserving leather, which consists in first cleaning the leather to be treated, applying volatile alcohol thereto and drying the leather, then applying to the latter a preservative composition of matter to form a thin coating thereon which comprises about 10% of Portland cement, about 45% of common tar, and about 45% of alcohol of the class consisting of ethyl and methyl alcohol, and finally drying the leather thus treated for a period of time ranging from several hours to twenty four hours with said composition of matter applied on said leather.
